At the place where motherhood meets entrepreneur and play dates collide with iPads, a new market for parent- and kid-friendly technology is exploding.

Family tech — Web services and applications for parents and kids — is a new market driven largely by mothers creating technology to solve problems that have plagued parents for decades, such as how to find a baby sitter, choose the right summer camp and capture the memories of their child's first year.

Family tech was the focus of a recent all-day event in Mountain View, Calif., the second conference of its kind backed by seed fund and start-up accelerator 500 Startups, which is led by Silicon Valley celebrity investor Dave McClure. Several of the hundreds of entrepreneurs gathered at the Microsoft Conference Center said that the busy and buzzy MamaBear Family Tech Conference validates the rising strength of the family tech market.

Like many entrepreneurs there, Brooke Chaffin, 42, left a tech job to pursue a project inspired by her kids. She had accumulated thousands of photos of her 1-year-old twin boys, but never moved them off her camera and into new photo albums, which still lay wrapped in plastic and collecting dust. Wracked with guilt, and knowing she was not alone, she set out to create an app that would help organize and share photos and videos.

Tayla Klein, a product marketing manager at Symantec, reacted to one of the speakers at the MamaBear Family Tech Conference in Mountain View, Calif., in May.

She pitched the idea to Disney Interactive, where she now runs the women and family division. Last week, her brainchild was released as an app called Story.

For Andrea Barrett, one unexpected struggle of motherhood was her son's marathon sleeping habits, which often meant she would be stuck at home for hours.

"We didn't have a baby sitter that we trusted. We ended up staying in a lot," said Barrett, 35. "Word-of-mouth is the way people want to find a caregiver, but it's very inefficient."

In 2011, Barrett launched UrbanSitter, an online service that connects parents with trusted baby sitters. No more Friday nights on the couch. The service is in 14 cities and raised $6 million in the fourth quarter last year, she said.

But it's not just women in this burgeoning space. Men, too, have recognized the potential of the market, among them the three founders of BabyJunk, an online marketplace to buy and sell baby and maternity goods. After becoming a dad, co-founder Garth Humbert watched barely worn children's clothes and toys pile up in his garage.

"It's just something that we needed or could use," Humbert said.

Women say they have taken the lead in family tech because they know how to design products that mothers, want — technology that is simple, helps them juggle their many responsibilities and supports their priorities — namely, their families.

Business leaders say they've barely touched the potential for family technology.

Women are "the superusers of technology," Chaffin said. "Women are the early adopters. When you make something that's a hit with women, you have a breakthrough."

Mothers are more likely to have a smartphone than teenagers, and 93 percent of them don't leave home without it, according to data from the conference. About one-third of mothers own a tablet. Women are online an average of almost three hours a day, and when a woman finds out she is pregnant, her Internet usage skyrockets. More than 70 percent of mothers have a Facebook page, and check it on average about five times a day.

But experts say the family tech industry, and the women leading it, still face hurdles. Baby-sitting and used onesies just aren't a sexy sell, which makes it difficult to secure funding.

"Technology has been built by young guys who want to do the next cool thing," said Chandini Ammineni, co-founder and CEO of ActivityHero, a site that helps parents find classes and camps for their kids. Family tech, she said, is often solving the problems of middle-class families.

While women have made inroads in Silicon Valley, several attendees said they still face sexism in the male-dominated industry. Most investors are men, and many have low expectations for female entrepreneurs.

Payday lenders got regulators to rethink rules on how closely to vet borrowers. E-cigarette makers got a delay in federal oversight of many vaping products. Candy makers praised a decision to hold off on more stringent labeling standards. And title insurers declared "victory" for getting changes that benefited them in the tax overhaul.

The Wisconsin Assembly planned to finish its work for the year Thursday by approving $350 million to build a new prison and provide all parents a $100 per-child tax rebate, although it's uncertain whether either will pass the Senate.
